VANT-GAN: adversarial learning for discrepancy-based visual attribution in medical imaging
Visual attribution (VA) in relation to medical images is an essential aspect of modern automation-assisted diagnosis. Since it is generally not straightforward to obtain pixel-level ground-truth labelling of medical images, classification-based interpretation approaches have become the de facto standard for automated diagnosis, in which the ability of classifiers to make categorical predictions based on class-salient regions is harnessed within the learning algorithm. Such regions, however, typically constitute only a small subset of the full range of features of potential medical interest. They may hence not be useful for VA of medical images where capturing all of the disease evidence is a critical requirement. This hence motivates the proposal of a novel strategy for visual attribution that is not reliant on image classification. We instead obtain normal counterparts of abnormal images and find discrepancy maps between the two. To perform the abnormal-to-normal mapping in unsupervised way, we employ a Cycle-Consistency Generative Adversarial Network, thereby formulating visual attribution in terms of a discrepancy map that, when subtracted from the abnormal image, makes it indistinguishable from the counterpart normal image. Experiments are performed on three datasets including a synthetic, Alzheimerâs disease Neuro imaging Initiative and, BraTS dataset. We outperform baseline and related methods in both experiments
Proximate and nutrient analysis of selected vegetable species: A case study of Karak region, Pakistan
Karak, an arid region, have limited water and land resources to cultivate various crops specially vegetables. However, a few seasonal vegetable are available to the local communities in meager quantities. The ash, carbohydrate, protein, moisture, fat, fiber contents, energy values and nutrient composition of eight vegetablesâ Abelmoschus esculentus, Spinacia oleraceae, Praecitrullus fistulosus, Luffa acutangula, Allium sativum, Amaranthus viridus, Chenopodium album and Momordica charantia were determined. Among these, A. sativum, S. oleraceae and C. album have the highest micro and macronutrients
Critical success factors for build-operate-transfer (BOT) projects in China
This study aims to create a list of CSFs for Chinaâs BOT projects to help organizations achieve project success. We first describe the role of CSFs in terms of three broad categories of whether BOT projects adopt strategies for risk transfer, the degree to which BOT projects foster the âwhole- life approachâ to project design and management and extent to which BOT projects ensure timely delivery and supplies good-quality products and services. Based on an initial CSF list, a questionnaire survey was conducted to identify the relatively important CSFs for BOT projects in China. Our initial assessment shows that the key CSFs corresponded to our defined categories of BOT projectsâ success factors. We then provide an updated list of CSFs with the top ten factors in ranking analysis. This list of CSFs could play a useful role in the phases of preparing, bidding, constructing, operating and transferring of BOT project
Constraint analysis of major problems facing the marine fisheries sector in accordance with the national fisheries policy of Pakistan
Pakistan is endowed with abundant fisheries resources that have significant economic potential. Capture fisheries contribute a comparatively vital role to the national economy. However, poverty, environmental degradation and political instability are major problems for the Pakistani people, and no effective steps have been taken to handle this socio-economically important sector efficiently in the past. Furthermore, the fisheries sector faced its own set of challenges, including the emergence of small-scale artisanal fisheries, the nonexistence of technologies, deficiency of institutional development, an absence of infrastructure, insufficient human resource skill, and a lack of responsiveness among fishing societies, all of which contributed to the sector's demise. The National Fisheries Policy (NFP) was formulated to address these problems in the fisheries sector. Potential efforts have been made by the Government of Pakistan to solve these constraints under various plans of objectives and strategy axes of the policy. Our findings indicate that despite these efforts, the fisheries sector does not show significant growth to achieve the policy goals. So, it is necessary to re-evaluate and re-orient this policy for further development of this sector. It is also essential to achieve the aim of Government of Pakistan Vision 2025 to become one of the 25th largest economies in the world
Ethno-botanical and geo-referenced profiling of medicinal plants of Nawagai Valley, District Buner (Pakistan)
The prime objective of the research was to list the important ethnomedicinal plants of Nawagai village, District Buner. During the survey, 44 plant species from 27 families were observed and collected from the targeted area of Khyber Pakhtunkhwa, Pakistan. Lamiaceae members were the most dominant (54%) followed by members of Asteraceae (30%), Poaceae (18%) and Solanaceae (12%). Relevant information such as field data, GPS coordinates family names, local names, therapeutic uses and plant habits were recorded for each species. For preservation purposes, specimens were mounted on herbarium sheets, and identified with the help of flora of Pakistan, flora of Australia and other relevant floristic records. During this research work all the collected specimens were preserved in the (BG&H, UOM) Botanical Garden and Herbarium, the data were also provided to the Department of Botany, University of Malakand Dir (Lower), Khyber Pakhtunkhwa, Pakistan.The prime objective of the research was to list the important ethnomedicinal plants of Nawagai village, District Buner.

Evidence for Isospin Violation and Measurement of Asymmetries in
We report the first evidence for isospin violation in and
the first measurement of difference of asymmetries between and . This analysis is based on the data sample
containing pairs that was collected with the Belle
detector at the KEKB energy-asymmetric collider. We find evidence for
the isospin violation with a significance of 3.1, \%, where
the third uncertainty is due to the uncertainty on the fraction of to
production in decays. The measured value is
consistent with predictions of the SM. The result for the difference of
asymmetries is \%, consistent with zero. The measured branching fractions and
asymmetries for charged and neutral meson decays are the most precise to
date. We also calculate the ratio of branching fractions of to .Comment: 11 pages, 7 figures. shown at FPCP2017. accepted by PR
